TEMPERATURES RESPONDING NICELY TO SUNNY SKIES. MINOR ADJUSTMENTS
TO TEMPERATURES...DEWPOINTS AND WINDS FOR THIS AFTERNOON BASED
ON TRENDS.

.SHORT TERM...(TODAY THROUGH SATURDAY NIGHT)
ISSUED AT 200 AM MST THU FEB 25 2016

PRETTY QUIET WEATHER PATTERN THROUGH THE FIRST HALF OF SATURDAY.
NORTHWESTERLY FLOW ALOFT WILL BE IN PLACE TODAY WITH RATHER WEAK
LLVL GRADIENTS. THIS WILL BE ONE OF THE LEAST WINDY DAYS IN AN
OTHERWISE QUIET WINDY MONTH. TEMPS WILL BE SEASONAL WITH HIGHS
MOSTLY IN THE 40S. HEIGHTS RISE ON FRI WITH LLVL WARM ADVECTION
AND 700 MB TEMPS UP TO AROUND 0C BY THE AFTN. THIS MEANS TEMPS
WILL RISE 10-15 DEGREES COMPARED TO TODAY. WITH WEAK FLOW ALOFT
(700 MB WINDS AROUND 20 KTS)...ANOTHER DAY OF RELATIVELY WEAK
WINDS WILL OCCUR.

THE FLOW ALOFT BECOMES MORE ZONAL BY SATURDAY AHEAD OF A RAPIDLY
MOVING SHORTWAVE. HIGHS WILL RISE INTO THE LOW TO MID 60S SO IT
WILL BE QUITE MILD FOR LATE FEB. WITH PRESSURE FALLS TO THE EAST
OF THE LARAMIE RANGE...WEST TO SOUTHWEST WINDS WILL REALLY BEGIN
TO INCREASE OVER SOUTHEAST WY DURING THE AFTN. THE 850 MB CAG-CPR
GRADIENT IS MAXIMIZED AT 65-75 METERS ON SATURDAY
EVENING...ASSOCIATED WITH THE SHORTWAVE TROUGH PASSAGE. WIND
HIGHLIGHTS WILL LIKELY BE NEEDED FOR THE WIND PRONE AREAS ON SAT
AFTN/EVENING. THERE IS ALSO SOME POTENTIAL FOR HIGH WINDS TO
SPREAD ONTO THE PLAINS OF SOUTHEAST WYOMING BEHIND THE FROPA ON
SAT EVENING. SOUNDINGS AT CYS SHOW GOOD SUBSIDENCE AND STRONG
WINDS JUST OFF THE SFC (65 KTS AT 750 MB). WHILE IT WILL BE BREEZY
TO WINDY THROUGH SAT NIGHT...WINDS WILL START TO DROP OFF BY
SUNRISE ON SUNDAY.

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 200 AM MST THU FEB 25 2016

UNSETTLED WEATHER IN THE EXTENDED WITH CHANCES FOR RAIN AND SNOW.

BOTH THE GFS AND ECMWF SHOW A SHORTWAVE MOVING THROUGH THE CWFA
SUNDAY. ECMWF A LITTLE FURTHER NORTH WITH THE ENERGY THAT WOULD
PRETTY MUCH LEAVE US DRY. GFS SHOWING MORE WIDESPREAD
PRECIPITATION...ESPECIALLY ACROSS OUR NORTHERN ZONES WHICH ITS
HITTING PRETTY HARD SUNDAY MORNING. CARRIED SLIGHT CHANCE POOPS
ACROSS CONVERSE AND NIOBRARA COUNTIES WITH CHANCE POPS FOR THE
MOUNTAINS OUT WEST. PRECIP SHOULD COME TO AN END SUNDAY AFTERNOON
AS THE SHORTWAVE MOVES EAST.

NEXT SHORTWAVE BEGINS TO IMPACT ZONES OUT WEST BY MONDAY
AFTERNOON. GFS AND ECMWF IN GOOD AGREEMENT ON TIMING AND LOCATION
OF PRECIP ACROSS CARBON AND WESTERN CONVERSE COUNTIES AS THE
FRONT SAGS IN FROM THE NORTH. WITH THE TIMING OF THIS SYSTEM
COMING THROUGH AT NIGHT...WOULD EXPECT MOST OF THIS PRECIP TO FALL
AS SNOW. GFS 700MB TEMPERATURES OF -6 TO -8C IS IN GOOD AGREEMENT
WITH THE ECMWF. THIS LOOKS TO BE A PRETTY GOOD TRACK...THE LOW
TRACKS ACROSS CENTRAL COLORADO...SO WE COULD BE LOOKING AT SOME
SNOW ACCUMULATIONS FOR MONDAY NIGHT INTO TUESDAY.

RIDGE AXIS BUILDS IN FOR WEDNESDAY FOR A DRY DAY. COULD BE QUITE
WINDY IN THE PANHANDLE WEDNESDAY AS GFS 850MB WINDS 45-50KTS.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)

POSSIBLE IN THE HIGH COUNTRY THIS AFTERNOON...WITH SPEEDS
INCREASING OVERNIGHT ALONG AND WEST OF I-25. THESE WINDS LOOK TO
SPREAD FURTHER EAST ACROSS THE PLAINS FRIDAY MORNING.

.FIRE WEATHER...
ISSUED AT 200 AM MST THU FEB 25 2016

AFTER A COOL DAY TODAY...TEMPERATURES WILL WARM FRIDAY INTO SATURDAY.
HIGH TEMPERATURES WILL RISE INTO THE LOW TO MID 60S TO THE EAST OF
LARAMIE RANGE ON SATURDAY.  THIS WILL CAUSE MINIMUM RELATIVE HUMIDITY
VALUES TO FALL TO 15-20 PERCENT.  BREEZY CONDITIONS WILL ALSO EXIST
ACROSS SOUTHEAST WYOMING...RESULTING IN AN ELEVATED FIRE WEATHER
THREAT.
